# The result line in input is in format:
# [time] $type-torture:--- End of test: $result: arg=value arg=value ...
#
# $type and $result are essential for a test.
# And for now, we care about the value of arg onoff_interval
# which represents doing cpuhotplugs or not.
#
# Now, there are three results here, 'RCU_HOTPLUG' and
# 'FAILURE' both represent the test failed.
